Apparatus and Method for Restricting File Operations

1. An information processing apparatus, comprising: a storage unit capable of storing first image data, second image data and management information indicating at least information about an attribute of the second image data, wherein the second image data is related to the first image data and is in a format different from that of the first image data; an acquiring unit which transmits license information on the first image data to a server connected to the information processing apparatus and acquires information on the operation restriction applied on the first image data sent from the server; an assigning unit which assigns attribute information based on the acquired information on the acquired operation restriction to the second image data; and a restricting unit which restricts an operation on the second image data based on the attribute information assigned to the second image data by the assigning unit.

2. The information processing apparatus according to claim 1 , wherein the first image data is image data derived from the second image data or the second image data is image data derived from the first image data.

3. The information processing apparatus according to claim 2 , further comprising: an image data generating unit which generates the second image data from an original image inputted to said image data generating unit; and a file converting unit which converts the second image data into the first image data.

4. The information processing apparatus according to claim 2 , further comprising an image data generating unit which receives print job data including the first image data and converts the received print job data to generate the second image data.

5. The information processing apparatus according to claim 1 , wherein said restricting unit comprises an encrypting unit which encrypts the second image data.

6. The information processing apparatus according to claim 1 , further comprising a display unit which displays a thumbnail image based on second image data related to a piece of first image data that is not prohibited to be displayed among the pieces of first image data stored in the storage unit.

7. A method performed in an information processing apparatus, comprising the steps of: storing in a storage unit first image data, second image data and management information indicating at least information about an attribute of the second image data, wherein the second image data is related to the first image data and is in a format different from that of the first image data; transmitting license information on the first image data to a server connected to the information processing apparatus and acquiring information on the operation restriction applied on the first image data sent from the server; assigning attribute information based on the acquired information on the acquired operation restriction to the second image data; and restricting an operation on the second image data based on the attribute information assigned to the second image data.

8. A non-transitory computer-readable storage medium storing, in executable form, a program for causing an information processing apparatus to implement a method, the method comprising the steps of: storing in a storage unit first image data, second image data and management information indicating at least information about an attribute of the second image data, wherein the second image data is related to the first image data and is in a format different from that of the first image data; transmitting license information on the first image data to a server connected to the information processing apparatus and acquiring information on the operation restriction applied on the first image data sent from the server; assigning attribute information based on the acquired information on the acquired operation restriction to the second image data; and restricting an operation on the second image data based on the attribute information assigned to the second image data.
